pipeline: raspberrypi: Fix possible null dereference
The freeBuffers() cleanup code calls into the IPA to unmap and free shared buffers. However, this function could be called before the IPA has opened (via registerCamera()), causing a segmentation fault. Fix this by guarding against calling the IPA if it has not been opened.
